PROVISIONAL PROGRAMME

Monday 1 December 2014: Means of Escape / Human Behaviour in Fires / UK and New EU Testing Standards
08.30 Registration and coffee
09.00 Regulatory framework, Nick Troth, Arup Fire: An overview of the development of UK Fire Safety legislation through history and insight into current UK fire safety legislation and guidance.
09.40 Introduction to compartment fires, Dr Roth Phylaktou, Energy Research Institute, University of Leeds: Importance of enclosures, phases of fire development, growth period, flashover, fully developed fire. Relation to life and property safety.
10.20 Coffee
10.35 Means of escape, Nick Troth, Arup Fire: Introduction, existing codes of practice, list of codes, guides and reports, comments and statistics, factors affecting means of escape, appreciation of the general issues, factors specific to the means of escape, definition of means of escape, ‘structural’, ‘escape’, ‘without outside assistance’, ‘place of safety’, ultimate safety, comparative safety, limiting conditions for tenability. Evacuation time, occupancy, the people in the building, number of occupants, density factor, distribution, calculation of minimum number of exits, distribution of alternative exits, staircases, travel distance. Horizontal and vertical evaluation – Worked Examples.
12.00 Lunch
13.00 Human behaviour in fire – basic principles, modelling and design, Dr Jeremy Fraser-Mitchell, BRE: Introduction; Movement speeds and flow rates; Motivation to evacuate; Causes of delay before evacuation; Exit /route choice; Merging flows/contra-flows; Capabilities of disabled people; Design behavioural scenarios. The talk will emphasise which aspects of human behaviour are / are not well understood, and where extra care is required in modelling and design.
15.00 Tea
15.15 Travel time as an alternative to travel distance, Stuart Martin, Buro Happold: The concept of travel distance as the criteria for assessing the adequacy of means of escape is limited and can be inflexible in use. Moreover, the majority of current design code distances are historic in origin and are not based on modern buildings or the fire safety systems provided therein. Travel time, determined by assessing occupant profile, fire risk, building geometry, passive and active fire protection provisions, generates a more flexible design assessment tool. When applied in conjunction with varying rates of travel a range of travel distances can be defined.
